ar walking may be the ultimate cardiovascular exercise. However, the circle walking exercise of Ba Gua Zhang is not simply walking. It combines the benefits of walking with Qi Gong and meditation. It also develops a refined strength that can be employed in martial arts and other physical activities.

Circle Walking Nei Gong is not only the foundation of Ba Gua's sophisticated fighting method, but also an incredible system of health preservation that nourishes life and staves off illness. Ba Gua Circle Walking Nei Gong is rooted in ancient Daoist longevity exercises and internal alchemy practices, which aim at re-connecting us to our intrinsic nature and inner wisdom.
